Krystol Internal Membrane™

Waterproofing admixture for concrete.

KIM is the world’s only permanent, self-sealing, corrosion-free, concrete waterproofer. KIM is a chemical admixture used for the treatment of concrete and concrete products to protect against water intrusion, leakage, cracking, chemical attack, and corrosion of reinforcing steel. KIM is a more reliable and cost-effective alternative to traditional waterproofing membranes because KIM turns the concrete itself into the membrane.

Krystol Hyperseal BR Waterstop™

Hydrophilic Butyl Rubber for in-situ concrete

Hyperseal BR is a high performance, hydrophilic butyl rubber waterstop, which swells to form a long-lasting water-tight compression seal. The swelling action is the result between water and hydrophilic groups which are part of the Hyperseal BR molecular structure.

Evolight S

Reoxthene Membrane – General Construction

Evolight S and Evolight S Mineral are plastomeric waterproofing membranes with outstanding performance. Made from latest generation Reoxthene ultralight technology distilled bitumen compound and polyester non-woven fabric carrier reinforced with glass-fibre threads. This membrane can be used in waterproofing all civil and industrial constructions (traditional, pre-fabricated and metallic).


Polyurethane membrane.

KGM-100 is a single component moisture curing polyurethane membrane, which is coated over surfaces to form a seamless watertight finish. When particular membrane molecules come in contact with moisture, KGM-100 cures to produce a solid but highly flexible material that will provide you with dependable waterproofing protection.

KGM-100 has a wide range of uses and is designed to waterproof most non-exposed external wet areas for above and below ground construction. Typical areas of application include retaining walls, planter boxes, balconies, non-exposed roof decks, elevator pits and equipment pits, detention tanks as well as tunnels and underground vaults.
